2 AMC-S402 Installation
This chapter contains the procedures for installing and removing the AMC-S402 AMC
module.
2.1 Installation and Removal of the AMC-S402 Module
The AMC-S402 AMC Module can be installed into an ATCA shelf (chassis) with slots
designed to accept AMC.3 installations. The module slot height must properly
match the panel height fitted to the AMC.
2.2 Important Information about Your Chassis
The AMC-S402 is designed to PICMG specifications and is a general-purpose
Advanced Mezzanine Card. Before using this board, review the specifications of the
chassis and backplane that will house the module to determine the presence of, and
any limitations of, chassis, IPMI bus, and user defined pin outs. For example, some
chassis backplanes route certain I/O pins to internal resources such as alarm cards
and drive resources. The AMC-S402 is intended for an ATCA AMC carrier card or
MicroTCA chassis/backplanes/slots that are AMC.3 compliant. It is your
responsibility to verify this system compatibility. Failure to do so could result in
improper operation or equipment damage.
2.2.1 Safety Statement
The AMC-S402 is designed to comply with UL60950-1, and is intended to be used
with similarly tested ATCA and MicroTCA products that have a user’s guide detailing
user installation of AMC module accessories.
2.2.2 Observe Maximum Module Current Requirements
Be sure to validate the host chassis, and the intended AMC slot is able to meet the
following maximum current requirements
Table 3 Max AMC Module Current Requirements
Max current draw AMC-S402

2.3.1 Observe ESD Precautions
Emerson strongly recommends that you use an antistatic wrist strap and a
conductive foam pad when installing or upgrading a system. Electronic
components, such as disk drives, computer boards, and memory modules, can be
extremely sensitive to electrostatic discharge (ESD). After removing the component
from its protective wrapper or from the system, place the component flat on a
grounded, static-free surface (and, in the case of a board, component side up). Do
not slide the component over any surface.
If an ESD station is not available, you can avoid damage resulting from ESD by
wearing an antistatic wrist strap (available at electronics stores) that is attached to
an active electrical ground. Note that a system chassis may not be grounded if it is
unplugged.
2.3.2 Watch for Bent Pins or Other Damage
Bent pins or loose components can cause damage to the board, the backplane, or
other system components. Carefully inspect your board and the backplane for both
pin and component integrity before installation. Our suppliers take significant steps
to ensure there are no bent pins on the backplane or connector damage to the
boards prior to leaving our factory. Bent pins caused by improper installation or by
boards with damaged connectors could void the warranty for the backplane or
boards.
If a system contains one or more crushed pins, power off the system and contact
your local sales representative to schedule delivery of a replacement chassis
assembly.
2.4 Use Caution When Installing or Removing AMC
When first installing boards in an empty chassis or onto a carrier card, we
recommend that you start at the left of the card cage and work to the right.
When inserting or removing a board in a slot adjacent to other boards, use extra
caution to avoid damage to the pins and components located on the primary or
secondary sides of the boards.

2.4.2 Understand Hot Swap
Your AMC-S402 is electrically designed for hot swap within a fully powered chassis.
To facilitate hot swap, there is a blue LED on the front faceplate. This LED is under
software control.
If your system is using software that provides full hot swap capabilities, the software
will illuminate the blue hot swap LED on the AMC faceplate when software has
stopped and it is safe to remove the AMC module.
If your system does not have hot-swap aware software running, behavior of the blue
LED is indeterminate. In this case, you may need to manually shut down applications
or operating systems running on the board prior to board removal, even if the blue
LED is lit.
Powering down or removing a board before the operating system or other software
running on the board has been properly shut down may cause corruption of data or
file systems.
2.5 Verify Slot Usage
Prevent possible damage to module components by verifying the proper
slot usage for your configuration.
In most cases, electronic keying (E-keying) will prevent power on of a board into an
incompatible slot. However, as an extra precaution, you should be familiar with the
slot purpose.

corruption of data or file systems.
3. If your module is hot swap compliant and you are running fully functional hot
swap-aware software, unlatching this ejector lever will start the shutdown
process on the board. The software will slowly blink the blue hot swap LED
indicating the module is in the process of being de-activated.
4. Once the module has been de-activated, the blue LED will solidly illuminate.
Once this is done, you can extract the m

3.3.1 SAS Port Isolation Multiplexor Circuit
The AMC-S402 includes SAS re-transmitter circuits that can be used to adjust or
“wave-shape” the transmit signal characteristics driven out the AMC finger
connections (storage signaling ports 2 and 3). At manufacturing time, this circuit is
pre-set to values that are optimal for the majority of deployments.
Programmable parameters include:
transmit pre-emphasis (five levels)
receiver equalization (three levels)
Transmit output swing to support SAS up to 1600mV
Tools are available to adjust these circuits to accommodate atypical backplane or
cable situations. Please contact your Emerson applications engineer if you feel your
deployment will require different settings.
